How- to books make up 0.3 of the books in the school library. Of these 0.2 deal with carpentry and 0.4 deal with electronics. 0.3×0.4=0.12

Interpret what the answer a.12 represents in this equation above.
A. The portion of the books in the library that are how-to books on electronics.
B. The portion of books in the library that are how-to books on carpentry.
C. The portion of the how-to books that are about either carpentry or electronics.
D. The portion of books in the library that are how-to books

C. The portion of the how-to books that are about either carpentry or electronics.

The correct interpretation of the answer 0.12 in the given equation is:

C. The portion of the how-to books that are about either carpentry or electronics.

To interpret the answer, we can break down the equation and the given information.

First, we know that how-to books make up 0.3 (or 30%) of the total books in the library.

Then, we are given that out of these how-to books, 0.2 (or 20%) deal with carpentry and 0.4 (or 40%) deal with electronics.

The equation 0.3 × 0.4 = 0.12 represents the product of the proportion of how-to books in the library (0.3) and the proportion of how-to books that deal with electronics (0.4).

Therefore, the answer 0.12 represents the portion of the how-to books in the library that are about electronics.

So, the correct interpretation is:
A. The portion of the books in the library that are how-to books on electronics.
